NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent N0.761,644, dated June 7, 1904.

Application filed February 14, 1903. Serial No. 143,443. (No model.)

To all whom it may concern:

Be it known that I, J OSEPH BART, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improvements in non-refillable bottles. It has for'its object to prevent the unauthorized refilling of the bottle after it has been emptied of its original contents. It is characteristic for simplicity of construction and cheapness of manufacture. It can also be expeditiously applied, the same requiring no marked departure from the usual construction of the bottle either as to its neck or other portion.

My invention consists of the construction, combination, and arrangement of parts, substantially as hereinafter more fully disclosed, and specifically pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a vertical sectional view of the bottle-neck with my improved stopper inserted therein. Fig. 2 is an end view looking into the mouth of the bottle. Fig. 3 is a sectional view taken: on the line 00 w of Fig. 1, showing the casing of cork upon the external surface of the plug. Fig. 4 illustrates the method of emptying a bottle provided with my im-.

Fig. 5 is a bottom View of the Fig. 6 is a detail sectional view showproved cork. valve.

ing the rabbetjoint connecting the plug proper with the valve-seat.

Referring more particularly to the drawings, 1 is a plug, preferably of porcelain or other suitable material, having upon its exterior cylindrical surface a circumferential groove 2 to receive a layer of cork or other expansible means 3. Said groove extends between the flanges 1 and 1 which serve to hold said layer of cork firmly upon the plug. The upper flange 1? will be seen in the drawings to be somewhat larger in cross-section than the flange 1", the purpose of which is that said upper flange may come'in contact with the flange L of the bottle-neck when the I stopper is inserted into ,the mouth of the bottle. Said upper end of said plug should conform approximately to the size of the interior of the opening at the mouth of the bottle in order that there may be no room for the insertion of any instrument for prying or otherwise extricating the plug when it is once inserted into the bottle-neck. A funnel-shaped opening 5 extends through the plug, beginning near its upper end in a very small aperture 5 and widens outwardly and downwardly.

In using my invention the plug is forced or pressed into the neck of the bottle until the upper flange 1 of the plug comes in contact with the flange 4c in the bottle-neck. It will be seen that as soon as the plug is inserted the conformity of the upper end of said plug to the interior of the neck will prevent any instrument being inserted for removing said plug without breaking the bottle-neck and that the cork covering or other expansible means clamp it securely into the bottle-neck, thus preventing it from being shaken or jarred therefrom. V

In emptying the bottle of its contents a shaking motion must be used, as seen in Fig. 4, because of the smallness of the opening 5". The opening in the bottle is so small as to practically prevent the refilling of the bottle.

The funnel shaped opening of the plug preferably widens out near the lower end of the plug into a chamber. Said chamber has grooves 6 in its upper funnel-shaped surface,

the function of which grooves is to increase the volume of said chamber, and thus increase the pressure upon thevalve 7 should an attempt be made to refill' the bottle. Housed within said chamber is a valve 7 which is tapering in form and has grooves 9 at its upper edge, as shown inFig. 5. The valve-seat 10 is formed separately from the plug and is preferably connected by means of the rabbetjoint, as shown in Fig. 6, and is held securely in place by the neck of the bottle and the cork surrounding the connection.

It will be readily seen that upon inverting a bottle provided with this stopper the valve will drop to the point 11, thus permitting the contents to flow through the grooves 9 on the edge of said valves. When an attempt is made to refill the bottle, however, the liquid poured into the stopper will serve to more firmly seat the valve by creating additional pressure thereon.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A bottle-stopper, substantially as described, having openings or grooves in the inner walls thereof, adapted to act as reservoirs, in combination with a valve, said valve having passages which extend from the upper face of the valve and open upon the seat of said valve, to close said passages in said valve.

2. A bottle-stopper, in two parts, of the character described, connected together by a gasket, which partially ineloses said parts, said stopper having grooves in the inner walls thereof adapted to act as reservoirs, in combination with a valve.

In testimonywhereof I ailix my signature in presence of two witnesses.
